Description

Wrench structure

The present invention relates to a wrench structure, which mainly refers to a wrench that can be easily rotated in a small space.

The conventional wrench mainly has a working end that can engage the end of the bolt, and has a rod portion corresponding to the working end in the radial direction, and can be biased by the rod portion so that the working end can rotate the bolt, but if the bolt is located in the concave position, the wrench is The working field cannot extend into the recessed joint bolt, and thus has a wrench which can be used for recessing as shown in Fig. 7. The wrench 1' has a working end 11' which can engage a bolt (not shown). Corresponding to the working end 11' axially parallel direction, a rod portion 12' is disposed. The top end of the rod portion 12' is provided with two jacks 121', 122' which are mutually perpendicular to each other and can be interspersed in the jack 121' or 122'. The crossbar 2' is such that the working end 11' can be engaged with a bolt (not shown) by the rod portion 12' extending into a deep recessed position during operation, the crossbar 2' can be easily grasped by the user's hand The rotation of the rod portion 12' and the working end 11' can be rotated by a bolt.

However, corresponding to the workplace rail 2 'position of the narrow space bar 2' can not rotate smoothly, it must be inserted a jack 121 'after rotation 90 ^o out rail 2' is inserted further jack 122 'is rotated, and The different insertion holes 121', 122' are alternately inserted through the crossbar 2' to smoothly rotate the bolts, resulting in a slow and inconvenient operation.

The purpose of this creation is to provide a wrench that can be easily rotated in a small space.

The wrench of the present invention has a working end capable of engaging a bolt, the working end can be matched with the bolt with an appropriate size and shape, and the rod end portion is disposed corresponding to the axial parallel direction of the working end, and the top end of the rod portion is configured to be engaged with the external ratchet wrench. The joint end.

The joint end of the present invention may have a shape that can be inserted into the socket of the ratchet wrench, and the cross section thereof may be square, hexagonal, hexagonal, dodecagonal or other shapes, and an elastic positioning body is disposed at the joint end.

The joint end of the present invention may have a sleeve hole engageable with the protruding drive end of the ratchet wrench, and the sleeve hole may be square, hexagonal, hexagonal, dodecagonal or other shape.

The detailed description of the present invention will be more clearly apparent from the following detailed description.

In the following embodiments, the same functional components of the present invention are denoted by the same drawing numbers. Referring to FIGS. 1 to 3, the wrench 1 of the first embodiment of the present invention has a working end 11 which can engage the bolt 2, and the working end 11 is The matching bolts 2 are appropriately sized and shaped, and are connected to the axially parallel direction of the working end 11 to provide a continuous bar portion 12, and the top end of the rod portion 12 is provided with an engaging end 13 engageable with the outer ratchet wrench 3.

The joint end 13 of the embodiment has a shape that can be inserted into the hole of the ratchet wrench 3, and has a cross section which can be square, hexagonal, hexagonal, dodecagonal or other shapes as shown in FIG. The end 13 is provided with an elastic positioning body 131.

As shown in FIG. 2, in the implementation of the present invention, the working end 11 of the wrench 1 can be extended into the concave position to engage with the bolt 2. The upper engaging end 13 of the rod portion 12 can engage the ratchet wrench 3 and can be supported by the ratchet wrench 3 The sleeve hole 31 is sleeved with the working end 11 to control the working end 11 to rotate the bolt 4, and the ratchet wrench 3 can be rotated in a small space for forward and reverse rotation, which has better space utilization and enables the creation of the present invention. It can be implemented in the narrow space outside the concave occasion and the concave occasion, and has better applicability and ease of use.

Referring to the second embodiment of the present invention, the second embodiment is similar to the first embodiment, and the difference is that the engaging end 13 of the wrench 1 can be engaged with the protruding driving end 41 of the ratchet wrench 4. The hole 132 is sleeved, and the sleeve 132 can be square, hexagonal, hexagonal, dodecagonal or other shape.

In this embodiment, the driving end 41 of the ratchet wrench 4 can be engaged with the sleeve hole 132. As shown in FIG. 5, the wrench 1 of the present invention can rotate the bolt 2 in a recessed space, and the present invention can be better adapted. .

Therefore, according to the above, the present invention can improve the convenience and suitability of the rotating bolt in the concave position and the narrow space position, and the foregoing embodiment is an example of the creation, and the foregoing embodiment is an example of the creation, not the creation. Restrictions, equivalent changes based on the spirit of this creation should also fall within the scope of this creation.
