ABSTRACT

MANUAL TENSIONING TOOL

A portable tensioning tool includes a push bar, a fixed handle with recessed plates for positioning movement, a locking disc, spring components and an unlocking bar, a drive handle connecting part which connects the plates for the adjusting movement and the locking plate and a front holder for the jaws. The drive handle has an integrated cam for driving the plates of the adjusting movement and the locking plate. With the unlocking bar, the manual clamping tool can be unlocked quickly.

PORTABLE TORCH TOOL

The present invention relates to a manual tightening tool, and more particularly to a simple design of a manual tightening tool having a drive handle with an integrated cam for driving the positioning plates and an unlocking latch for the use of stored energy.

Many clamping tools are known. The U.S. Patent No. 7513492 shows a clamping tool, which is referred to as "manual quick release" and the inventor is present. The design of the manual quick release includes an adjustment rod, a locking pin and a second clamping block.

The adjustment bar divides the locking pin, a set of alignment layers and the locking layers. A first clamping block is seated in a predetermined position on the adjusting rod and a second is placed at the upper end of the locking pin. A drive handle is rotatably mounted on the safety pin, a movable shaft in the safety pin and an axial shaft placed opposite thereto. When the drive handle is pressed, the upper end of the drive shaft presses the top shaft.

Due to the top shank, the axial shank presses the adjusting and locking layers. And the movement of the layers drives the adjustment rod in one direction. This triggers a sponge or stretching function The design of the clamping tool is functional, yet it requires a large number of components, increasing the cost and complexity of the instrument. Therefore, there is room for improvement.

In addition, the openings of the alignment layers and the arresting layers for the alignment are I-shaped. The adjusting rod can be moved up and down along the openings of the adjusting and locking layers, whereby erroneous movements occur and the clamping function is impaired.

The present invention has been developed in view of these circumstances. It is an object of the present invention to provide a portable tightening tool which has a simple structure and is easy to use.

To achieve this and other objects of the present invention, a portable tightening tool includes a push bar, a fixing handle having at least one adjusting plate, a stopper plate, a plurality of spring components, and an unlocking bar, a drive handle, a connecting pin which has at least one passageway plate , a locking plate and a first jaw connects. The drive handle has an integrated cam to move the actuator plates and the locking plates. With the unlocking bar, the manual clamping tool can be unlocked quickly.

In addition, at least one actuator plate and one detent plate define an inverted "T" hole. The connecting pin is flat and has a two-stage broad and end part and a narrow elongated neck that connects the stepped end parts together.

The connecting pin through the inverted T-holes is taken in by at least one adjusting plate and a locking plate and then deflected by a 90 degree angle so that the stepped width and end portions thereof into the respective lower ends of the inverted T-holes of grab at least one plate for adjusting movement and a locking plate. In this way, the connecting pin can not be displaced vertically to at least one plate for adjusting movement and a locking plate and functional abnormalities can be prevented.

Figure 3 is a schematic sectional view of the present invention showing the portable tensioning tool in plumbing work.

is according to an illustration of the portable tensioning tool in unlocked mode.

According to - a portable clamping tool according to the present invention is shown. The portable clamping tool contains a sliding bolt 1 , a fixing handle 2 with a large number of integrated plates for positioning movement 5 , with at least one locking plate 6 , several spring components 7 and an unlocking bolt 8th , a drive handle 3 and a first jaw 4 ,

The sliding bolt 1 is in the fixing handle 2 , the drive handle 3 , the first jaw 4 , the plate for positioning movement 5 and the arresting plate 6 ,

The fixing handle 2 supports the sliding latch 1 , which has a second jaw 21 at the top, a handle 22 at the bottom, two spring chambers 23 . 24 at the bottom, a spring chamber 25 on the inside, a wall hole 26 on the handle 22 and a spring-loaded hole 27 on the handle 22 even on the lateral side of the wall hole 26 features.

The drive handle 3 comprises a single component in which a spring-loaded hole 31 at the top for connection to the fixing handle 2 , a cam unit 32 on the inside near the spring-studded hole 31 ( ) and a transverse connection 33 in the middle part for grasping the sliding bolt 1 is integrated.

The first jaw 4 is at one end of the sliding bolt 1 attached while holding a first clamp 41 that the second clamp 21 is opposite.

The plates for adjusting movement 5 are steel plates, each with a through hole 51 for grasping the sliding bolt 1 and a connection hole 52 for the passage of the connecting pin 53 fitted. Through the respective through hole 51 grab the plates for body movement 5 in the sliding bolt 1 with their respective ends from the cam component 32 the drive handle 3 be arrested. Through the cam components 32 can the drive handle 3 Actuate the plates for adjusting movement.

The locking plate 6 is the plate for positioning movement 5 similar and includes a through hole 61 to the sliding latch 1 as well as a lower connection hole 62 for the connection to the connecting pin 53 , In addition, the lower end of the locking plate 6 against the unlocking bolt 8th pressed.

The spring components 7 are each in the spring holding chambers 23 . 24 . 25 housed and through the plates for adjusting movement 5 or the locking plate 6 limited.

The unlock bar 8th is resilient in the spring-loaded hole 27 of the fixing handle 2 let in, with one end in the wall hole 26 of the handle 22 engages and the other to the lower end of the locking plate 6 is gehackt.

When using the portable clamping tool, the drive handle should 3 be pressed to the cam parts 32 in the plates for adjusting movement 5 and let them into the respective position and the sliding latch in the energy storing (or extended) mode (see ) to move. When the stored energy is drained, the unlocking latch should be off 8th be pressed lightly to the angular position of the plates for adjusting movement 5 and the locking plate 6 to correct. This turns the plates into place 5 and the locking plate 6 (Please refer ) and return the tool to its original state.

According to the present invention, the manual chuck tool has its limited number of parts, thereby reducing production costs and overhead for assembly. Through the integrated cam components 32 becomes the drive handle 3 usable by the plates for adjusting movement 5 and the locking plate 6 drive. This makes structure and assembly easy.

In addition, the said spring components 7 Compression springs. Nevertheless, even stretchable springs or equivalent components can be used as a replacement.

Furthermore, the unlocking 8th on the inside of the handle 22 for operation by finger to move the plates for positioning movement 5 or the locking plate 6 which triggers the same effect as unlocking the manual tightening tool. This does not apply to the example where the unlocking bolt 8th on the outside of the handle 22 is appropriate. Any change in the attachment or structural design of the Entsperrrigel 8th can be made without changing the idea and character of the invention.

According to the preferred assembly, the ends of the communication holes 52 from each plate for adjusting movement 5 and the lower connection hole 62 on the locking plate 6 be formed to inverted "T" holes. In addition, the connecting pin 53 a flat pencil with two-step wide and end parts 531 and a long neck 532 , the stepped broad and final parts 531 combines.

The connecting pin 53 is through the communication holes 52 at the plates for Stellebwegung 5 and the lower connection hole 62 let into the lock plate and then deflected at a 90 degree angle, so that the respective stepped wide and end parts 531 in the respective lower ends of the lower communication holes 52 . 62 to grab. This will be the connecting pin 53 from vertical displacement to the plates for positional movement 5 and the locking plate 6 held, so that functional abnormalities of the plates for Stellebwegung 5 and the arresting plate 6 be prevented.

Although the assembly of the present invention has been described in detail, variations or extensions to the invention may be made without prejudicing their idea or character.
