Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure, as the terms used are used to describe particular embodiments only, and are not intended to limit the exemplary embodiments based on the disclosure.

Fig. 1 shows a wrench for narrow space, which comprises a vertical rod 1, a handle 2 and a U-shaped head 3 for clamping a nut. Fig. 3 shows, pole setting 1 is including the first connecting portion 11 that the cross section that sets gradually is regular hexagon, the cross section is circular shape straight section 12 and the cross section is regular hexagon's second connecting portion 13, the diameter of straight section 12 is greater than first connecting portion 11's circumscribed circle diameter, also is greater than simultaneously the circumscribed circle diameter of second connecting portion 13. It is preferable that the diameters of the circumscribed circles of the cross sections of the first connection portion 11 and the second connection portion 13 are equal.

As shown in fig. 2, one end of the handle 2 is fixedly connected to a first sleeve 4, the first sleeve 4 is an inner hexagonal sleeve matched with the first connecting portion 11, the first connecting portion 11 can be just completely inserted into the first sleeve 4, and a central axis of the handle 2 is perpendicular to a central axis of the first sleeve 4. The length of the first sleeve 4 is preferably 1/2 greater than the length of the upright 1. Fig. 4-6 show that the end of the U-shaped head 3 away from the opening is a connection end 31, the connection end 31 is provided with a second sleeve 32, the second sleeve 32 is a hexagon socket matched with the second connection portion 13, the second connection portion 13 can be just inserted into the second sleeve 32 completely, and the central axis of the second sleeve 32 is parallel to the axis of the opening of the U-shaped head 3. The second sleeve 32 is fixedly connected to the connecting end 31 in the drawings, but may be formed by the connecting end 31 itself with a deep hole having an inner hexagonal shape.

The first sleeve 4 is sleeved on the first connecting portion 11, the second connecting portion 13 is inserted into the second sleeve 32, the U-shaped head portion 3 is clamped with a nut to be screwed, the handle 2 is held by a hand to enable the upright rod 1 to drive the U-shaped head portion 3 to rotate, and then the nut is screwed to be screwed or unscrewed. The inner side of the opening of the U-shaped head part 3 is provided with a sheet-shaped first magnet 34, so that the nut can be taken and placed conveniently. The end part of the second connecting part 13 is fixedly provided with a second magnet 14, so that the U-shaped head part 3 can be effectively prevented from falling off from the second connecting part 13. The handles 2 are preferably arranged to be 2 and symmetrically arranged on the first sleeve 4, and two hands respectively hold one handle 2 to jointly rotate the upright rod 1, so that a larger torque can be provided for the U-shaped head part 3, and the nut can be screwed up more tightly or can be easily screwed down from the screw rod. The handle 2 is provided with an anti-slip sleeve 21 or anti-slip threads 21, so that the hand slip is prevented in the process of screwing the nut.

When the second sleeve 32 is fixedly connected to the connecting end 31, a regular hexagonal connecting deep hole 33 is formed in a side wall of the connecting end 31 opposite to the opening of the U-shaped head portion 3, and the connecting deep hole 33 is matched with the first connecting portion 11 or the second connecting portion 13. When the diameters of the circumscribed circles of the cross sections of the first connecting portion 11 and the second connecting portion 13 are equal, the connecting deep holes 33 can be matched with the first connecting portion 11 and the second connecting portion 13. When the nut is in the non-narrow space, just can use as ordinary spanner in connecting deep hole 33 with first connecting portion 11 or second connecting portion 13 disect insertion, increased the utility model discloses an application scope.
