Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a socket wrench comprises a handle 1, a positioning mechanism and a rotating mechanism are arranged on the handle 1, the rotating mechanism comprises a supporting seat 4, two rotating shafts 5 are symmetrically arranged on the side wall of the supporting seat 4, the supporting seat 4 is rotatably connected with the handle 1 through the two rotating shafts 5, therefore, the supporting seat 4 and the handle 1 can rotate relatively, the lower end surface of the supporting seat 4 is symmetrically provided with a plurality of positioning columns 12, the upper end surface of the supporting seat 4 is fixedly provided with the ratchet wheel 7, the upper surface of the supporting seat 4 is provided with a damping rotating shaft, the damping rotating shaft is rotatably connected with a round table 15 and a connecting rod 8, the side wall of the round table 15 is fixedly connected with a spring 11, the bottom surface of the connecting rod 8 is rotatably connected with a locking claw 10, and the stopping pawl 10 is elastically connected with the spring 11, and the stopping pawl 10 can slide on the tooth back of the ratchet wheel 7 only after a certain force is applied to the connecting rod 8.

The handle 1 is provided with a rectangular groove, two clamping grooves are symmetrically formed in the inner side wall of the rectangular groove, the positioning mechanism comprises a fixing block 2, the fixing block 2 is located in the rectangular groove, a push rod 13 is fixedly mounted on the side wall, parallel to the rotating shaft 5, of the fixing block 2, buckles 14 are symmetrically arranged on the side wall, perpendicular to the rotating shaft 5, of the fixing block 2, the two buckles 14 can be clamped with the corresponding clamping grooves, and a positioning cylinder 3 is fixedly arranged on the upper surface of the fixing block 2.

The up end of connecting rod 8 is provided with sleeve 9, is provided with antiskid cover 6 on the lateral wall of connecting rod 8, and the staff also can easily rotate connecting rod 8 under the condition that has the greasy dirt on hand.

The depth of the rectangular groove is larger than the height of the positioning column 12, and after the push rod 13 is pressed down, the positioning column 12 can be completely separated from the positioning cylinder 3.

The height of the positioning column 12 is the same as that of the positioning cylinder 3, and the positioning column 12 can be completely clamped in the positioning cylinder 3.

The spring 11 is in a compressed state when the holding pawl 10 is at rest, forcing the holding pawl 10 into contact with the back of the teeth of the ratchet 7.

The utility model discloses during the use, install the sleeve 9 that corresponds the specification on connecting rod 8 earlier, rotate connecting rod 8 with same direction again, the lateral wall cover of connecting rod 8 has antiskid cover 6, even if the staff is stained with the greasy dirt and also can easily rotate connecting rod 8 on hand, 8 bottoms of connecting rod rotate the locking pawl 10 of connecting and can slide on the back of the tooth of ratchet 7 this moment, because spring 11 is in compression state always, so spring 11 forces locking pawl 10 and ratchet 7's the back of the tooth to keep in contact, after adjusting sleeve 9's angle, rethread supporting seat 4 changes sleeve 9's sensing.

Before rotating supporting seat 4, push rod 13 is pressed down first, make fixed block 2 atress move down, buckle 14 of fixed block 2 both sides can be in compression state because the effect of inside elastic connection spare, fixed block 2 consequently glides in the rectangle recess, a location section of thick bamboo 3 and reference column 12 alternate segregation, then rotate supporting seat 4, can make different reference column 12 and a location section of thick bamboo 3 looks block, because each reference column 12 all represents a directive position of sleeve 9, so confirm the position of supporting seat 4 after, upwards promote push rod 13, make two bayonets 14 move to the draw-in groove that corresponds, just can make reference column 12 insert in a location section of thick bamboo 3, just so just can realize the arbitrary directive regulation of sleeve 9.

When needing the installation, when dismantling the bolt, the extension bar that corresponds the specification is installed to the lower extreme at handle 1, rotates the extension bar, and power passes to ratchet 7 department through supporting seat 4, because the direction of installation, dismantling the bolt is opposite with the angle of adjustment direction of connecting rod 8, so pawl 10 prevents the ratchet 7 rotation, and power just can pass through pawl 10 and transmit to connecting rod 8 on, because be fixed mounting between connecting rod 8 and the sleeve 9, so through above-mentioned step, just can realize the installation or the dismantlement of bolt.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
