Abstract
The utility model discloses a multifunction wrench which is used for loosening and fastening a fastening piece. The multifunction wrench is composed of a handle and a wrench head. A ratchet wheel mechanism is arranged in the wrench head, and the ratchet wheel mechanism comprises ratchet wheels and ratchet pawls. The middle part of the ratchet wheel is provided with a cavity body, a screw rod and two movable clamping heads are arranged in the cavity, and the screw rod is axially fixed in the cavity body. In addition, a spiral spring is arranged between the screw rod and the ratchet wheel, the two movable clamping heads are sheathed on the screw rod through screw threads, and a clamping head opening and closing controlling mechanism is also arranged on the wrench. The multifunctional spanner can quickly clamp the fastening piece and has the advantages of simple operation and convenient carrying. So the utility model is an ideal mechanical tool.
Description
The utility model relates to a kind of spanner.
Spanner is a kind of machine tool commonly used.Spanner generally can be divided into two types: back-up wrench and monkey wrench.Because varying in size of securing member used back-up wrench need be equipped with one and overlapped several, carries and use all inconveniences.Monkey wrench uses more at present, and it is to adopt screw mandrel to regulate the active chuck of driving end, is applicable to the securing member in the certain size scope.But monkey wrench also exists many defectives, mainly shows: 1, regulate inconvenience, when the securing member change in size, need rotary screw rod to regulate; 2, use inconvenience, when the securing member periphery has when stopping, spanner must be taken off and reselect angle and carry out work.The multifunctional wrench that Chinese patent 93214092.0 provides is to have several square holes and plum blossom hole on the handle of monkey wrench.Although this method has certain effect, can not fundamentally address the above problem.
The purpose of this utility model is at the existing the problems referred to above of present spanner, and a kind of multifunction active wrench easy to carry, simple to operate is provided.
The purpose of this utility model is to realize by following technical proposal: this multifunction active wrench is made up of the driving end of handle and handle end, be provided with ratchet mechanism in the driving end, this ratchet mechanism is made up of ratchet and pawl, in the middle of the ratchet is cavity, be provided with screw mandrel and two active chucks in the cavity, screw mandrel is axially fixed in the cavity, and be provided with scroll spring between screw mandrel and the ratchet, screw thread is arranged on the screw mandrel, the screw thread of its left-half is opposite with the hand of spiral of right half part, and two active chucks are connected on the screw mandrel by thread bush.In addition, chuck folding controlling organization also is set on this spanner.When using this multifunctional wrench degree of tightness securing member, at first, two chucks are opened, clamp securing member by chuck folding controlling organization rotary screw rod; Pull handle then back and forth,, so just can tighten or ease out securing member because ratchet mechanism can only rotate securing member along a direction.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is elaborated.
Fig. 1 is the schematic diagram of this multifunctional wrench.
Fig. 2 is the cutaway view of Fig. 1 along A-A.
Fig. 3 is the schematic diagram of ratchet in this multifunctional wrench.
Among the figure, 1, driving end; 2, handle; 3, ratchet; 4, ratchet; 5, screw mandrel; 6, scroll spring; 7, chuck; 8, steel wire rope; 9, pulley; 10, push-and-pull key; 11, tuning key.
As depicted in figs. 1 and 2, this multifunctional wrench comprises parts such as driving end 1, handle 2, ratchet 3, ratchet 4, screw mandrel 5 and chuck 7.Two chucks 7 connect with screw mandrel 5 by screw thread.By rotary screw rod 5, just can control the folding of chuck 7.In the present embodiment, chuck folding controlling organization is made up of with the push-and-pull key 10 that is connected with steel wire rope 8 outer ends the steel wire rope 8 that twists on the screw mandrel 5, and push-and-pull key 10 is arranged on the handle 2.Like this, the operator is as long as pulling push-and-pull key 10 just can make screw mandrel 5 rotate by steel wire rope 8, and two chucks 7 open; After unclamping push-and-pull key 10, screw mandrel 5 can merge chuck 7 in the effect lower edge of scroll spring 6 counter-rotation.In order to prevent steel wire rope 8 wearing and tearing, also be provided with pulley 9 on the driving end 1, steel wire rope 8 is by this pulley 9.
But the ratchet mechanism in this driving end 1 adopts the break-in ratchet mechanism.The shape of ratchet 4 as shown in Figure 3.Ratchet 4 is connected with tuning key 11 on the handle 2.Rotate tuning key 11, the rotation direction that can regulate ratchet 3 all can be used this spanner when being screwed into or ease out securing member.
The multifunctional wrench that the utility model provides compared with prior art has following advantages:
1, owing to adopt the folding of push-and-pull key control chuck, regulate very conveniently, can clamp fast Securing member;
2, but the break-in ratchet mechanism is set on the driving end, is screwed into or eases out securing member and all can advance OK, and the energy continuous operation, need not to take off, greatly improved work efficiency.
