Description

Technical Field

[0001] The present application relates to the technical field of ratchet wrenches, and in particular to a locking and positioning ratchet wrench. Background Art

[0002] A ratchet wrench is a manual screw tightening tool. Single-head and double-head ratchet wrenches with multiple specifications and movable handles are connected by a main plum blossom sleeve and a slave plum blossom sleeve of different specifications and sizes through the engagement of the female key and the male key of the hinge key. Since a plum blossom sleeve has two specifications of plum blossom through holes, it can be used to tighten or loosen screws of two specifications, thereby expanding the scope of use and saving raw materials and labor costs. The movable handle can easily adjust the use angle of the wrench. This wrench is used for tightening and loosening screws and has the characteristics of strong applicability, easy use and low cost.

[0003] Existing ratchet wrenches generally need to be used with sockets of different types. When different types of hexagonal screws are removed, different types of sockets need to be used for the operation. This results in the need to carry a large number of sockets at the same time, which is troublesome and laborious, and reduces the flexibility and practicality of the ratchet wrench. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present application provides a locking and positioning ratchet wrench, which has the advantages of being able to adjust the ratchet wrench according to the size of the hexagonal screw, so that the ratchet wrench can be adapted to various types of hexagonal screws for use, avoiding the need to use a socket to remove the hexagonal screws, etc. It solves the problem that the existing ratchet wrenches generally need to be used with different types of sockets. When removing different types of hexagonal screws, different types of sockets need to be used, which results in the need to carry a large number of sockets at the same time, which is more troublesome and laborious, and reduces the flexibility and practicality of the ratchet wrench.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a locking and positioning ratchet wrench, comprising a main body, a ratchet is rotatably connected inside the body, the bottom surface of the ratchet is fixedly connected to a base, six equidistantly arranged threaded rods are rotatably inserted inside the base, the outer circumference of each threaded rod is threadedly connected to a threaded tube, the outer circumference of the threaded tube is fixedly connected to a connecting plate, the bottom surface of the connecting plate is fixedly connected to a positioning plate, a control rod is rotatably inserted inside the base, the front side of the body is fixedly connected to a fixing plate, and the outer surface of the fixing plate is slidably sleeved with a shell.

[0006] Through the above scheme, since the existing ratchet wrench generally needs to be used with sockets of different models, when different models of hexagonal screws are removed, different models of sockets need to be used for the operation, which results in the need to carry a large number of sockets at the same time, which is more troublesome and laborious, and reduces the flexibility and practicality of the ratchet wrench. The active gear drives the threaded rod to rotate under the action of the driven gear, prompting the threaded tube to drive the connecting plate and the positioning plate to retract and move, thereby locking and positioning hexagonal screws of different models, which is convenient for the disassembly of hexagonal screws of different models.

[0007] Furthermore, six limiting grooves are provided inside the base, and the outer surface of the positioning plate is slidably connected to the base through the limiting grooves.

[0008] Through the above solution, the threaded tube is restricted to prevent the threaded tube from rotating along with the threaded rod, so that the positioning plate is always moved laterally.

[0009] Furthermore, a first limiting ring is fixedly sleeved on the outer circumferential surface of each threaded rod, and the outer circumferential surface of the first limiting ring is rotatably connected to the inside of the base.

[0010] Through the above solution, the threaded rod is restricted to prevent the threaded rod from sliding and deviating, thereby increasing the stability of the threaded rod movement.

[0011] Furthermore, a driven gear is fixedly sleeved on the outer circumferential surface of each threaded rod, a driving gear is fixedly sleeved on the outer circumferential surface of the control rod, and the driven gear is meshed with the driving gear.

[0012] Through the above scheme, the driving gear can drive all the threaded rods to rotate synchronously under the action of the driven gear, so that the positioning plates can be retracted and extended synchronously.

[0013] Furthermore, a second limiting ring is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the second limiting ring is rotatably connected to the inside of the base.

[0014] Through the above solution, the control rod is restricted to prevent the control rod from sliding longitudinally, thereby increasing the stability of the control rod movement.

[0015] Furthermore, a knob is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the knob is provided with anti-slip grooves arranged at equal distances.

[0016] The above solution makes it convenient for the user to rotate the control rod through the knob and prevents the user from slipping.

[0017] Furthermore, a handle is fixedly connected to the front surface of the shell, and an anti-slip sleeve is fixedly sleeved on the outer circumferential surface of the handle.

[0018] The above solution makes it convenient for the user to take, place and use the ratchet wrench through the handle, and prevents the user's hand from slipping.

[0019] Furthermore, bolts are slidably inserted inside the shell, and positioning grooves arranged at equal intervals are provided inside the fixing plate, and the bolts are threadedly connected to the fixing plate through the positioning grooves.

[0020] Through the above scheme, the outer shell can be positioned by the bolts and the positioning grooves, thereby facilitating the adjustment of the length of the ratchet wrench, making it easier for users to use.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The locking and positioning ratchet wrench drives the threaded rod to rotate under the action of the driven gear through the active gear, so that the threaded tube drives the connecting plate and the positioning plate to retract and move, thereby achieving the effect of being able to adjust the ratchet wrench according to the type of hexagonal screw, facilitating the positioning and removal of hexagonal screws of different types, and solving the problem of needing to use different types of sockets to remove hexagonal screws of different types, which results in the need to carry a large number of sockets at the same time, which is troublesome and laborious, and reduces the flexibility and practicality of the ratchet wrench.
