Detailed Description

The present invention will be further described with reference to the accompanying fig. 1-6.

A cylindrical stable multifunctional wrench, as shown in fig. 1, mainly comprising: the handle 1, the connecting handle 3 and the clamping hook 5;

as shown in fig. 2, the handle 1 is a rectangular parallelepiped structure, and one end of the handle is a hand holding area, i.e. a handle 101; the other end is fixedly connected with the connecting handle 3. As shown in fig. 3, the connecting handle 3 is a strip-shaped connecting piece, and one end far away from the handle 1 is rotatably connected with the hook 5 through the first pin 2; preferably, the stem 3 comprises a straight section 301; the straight section 301 has a first pin hole 302 at one end thereof near the hook 5 and is engaged with the first pin 2. Two second pin holes 303 are arranged in parallel at one end of the straight section 301 close to the handle 1; a second square groove 103 is formed in the end face of the connecting end of the handle 1, one end, close to the handle 1, of the straight section 301 is inserted into the second square groove 103, two through holes 102 are formed in two side faces of the second square groove 103, the through holes 102 correspond to the second pin holes 303 in one-to-one mode, and the through holes 102 and the second pin holes 303 are identical in size; a second stud pin 4 is mounted in the through hole 102. Thus, the handle 1 and the connecting handle 3 can be fixed by two hinged positions.

As shown in fig. 4, the hook 5 is a hook structure, and the root is a double-lug structure; the double-lug structure comprises a first square groove 501 and a connecting hole 502; preferably, the hook-shaped end of the hook 5 includes three parts, namely a first bending part 503, a second bending part 504 and a third bending part 505, which are respectively straight structures and are connected in sequence; wherein, an included angle structure is formed between two adjacent bending parts. The inner sides of the three parts form a semi-open polygonal area together with the first arc part 304. The part of face for the face of cylinder can effectively be held to the centre gripping, has avoided the fish tail of sharp-pointed department to the part surface moreover. The connecting end of the connecting handle 3 and the hook 5 is nested in the first square groove 501, and the end extends outwards along the length direction and protrudes outwards from the end surface of the first square groove 501.

The inner side end surface of the straight section 301 protruding out of the end of the first square groove 501 is composed of two arc surfaces, and the cross-sectional area at the arc surface shrinks in the direction of extension, specifically referring to fig. 1 and 3, which are respectively a first arc part 304 and a second arc part 305, wherein the arc radius of the second arc part 305 is smaller than that of the first arc part 304.

Preferably, as shown in fig. 1-4, the corners of the handle 1, the connecting handle 3 and the hook 5 are all processed into a rounded structure, so that not only the grip feeling is good, but also the workpiece is prevented from being damaged.

Preferably, a small amount of anaerobic locking agent is coated between the first pin 2 and the second pin 4 and the corresponding mounting positions to form a cementing structure, so that on one hand, additional mounting structures are reduced, on the other hand, the pins can be fixed, but the contact positions of the pins and the hooks 5 are not subjected to gluing treatment, so that the hooks 5 can normally rotate around the connecting holes 502 within a certain range.

The use of the wrench in this embodiment can be seen in connection with fig. 5 and 6. Firstly, the hook 5 is pulled away to be clamped into the head end of the spring positioning needle, then the handle 1 is held to drive the connecting handle 3 to be stressed in the opposite direction to clamp the head end of the spring positioning needle, so that the head end of the spring positioning needle cannot swing left and right (as shown in figure 5), and finally the pressure head is fastened on the spring positioning needle (as shown in figure 6, wherein a chain line is the installation direction).

The above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
