Description

Torque screwdriver

This creation relates to hand tools, more specifically a torque screwdriver.

According to the general torque screwdriver, the torque value can be adjusted to tighten or loosen different objects, thereby avoiding damage to the objects and related parts. However, in addition to being able to adjust the torque value, a general torque screwdriver also comes with a variety of different types of screwdriver bits for users to use accordingly according to the appearance of different objects. However, some torque screwdrivers and the screwdriver bits are stored separately, so the screwdriver bit is often lost or cannot be found temporarily. Of course, there are also some torque screwdrivers that combine the screwdriver heads with the back cover of the torque screwdriver to reduce the space occupied during storage. However, the method of combining the screwdriver heads with the back cover requires special features except for the back cover. design, which will lead to a significant increase in mold opening, manufacturing, assembly and other costs. Moreover, in use, the back cover must be unscrewed or tightened from time to time, and no matter in the process of unscrewing or tightening, the screwdriver head will The back cover rotates synchronously, which may easily cause the screwdriver head to fall off or loosen under long-term use.

In view of this, in order to improve the previous technology, the screwdriver head attached to the conventional torque screwdriver has problems such as inconvenience in use, high costs of mold opening, manufacturing, and assembly, and the screwdriver head is easy to fall off and loosen. For this reason, The present invention provides a torque screwdriver, which includes: a main body with a front seat, a coupling head coupled to the front end of the front seat, a rear seat and a clutch unit. The clutch unit is coupled to the rear end of the front seat and the front seat. between the front ends of the rear seats, so that the rear seats can be pulled back and temporarily separated from the front seats, and after rotating the rear seats to adjust the torque value, the rear seats are released and rejoined with the front seats, The rear end of the rear seat has an accommodating chamber extending axially inward; an accommodating seat is detachably placed in the accommodating chamber of the screwdriver body; a plurality of sockets are formed on one end of the accommodating seat; a plurality of screwdriver heads are formed , are detachably inserted into each socket of the accommodation base; a back cover is detachably combined with the rear end of the rear seat of the screwdriver body to close the accommodation chamber; thereby achieving convenience of use , lower cost, not easy to fall off, lose, and can reduce the volume during storage.

In order to enable your review committee to have a further understanding and recognition of the features and characteristics of this creation, the following preferred embodiments are listed below and explained with drawings: Please refer to Figures 1 to 4, which is a preferred embodiment of the present invention providing a torque screwdriver 100, which mainly includes a screwdriver body 10, a receiving seat 20, a plurality of screwdriver heads 30, and a back cover 40 and a cushion 50, wherein: Please refer to the first to fourth figures. The screwdriver body 10 has a front seat 11 , a combination head 12 , a rear seat 13 and a clutch unit 14 . The coupling head 12 is coupled to the front end of the front seat 11 for detachable coupling with any starter head. The clutch unit 14 is coupled between the rear end of the front seat 11 and the front end of the rear seat 13 to The rear seat 13 can be pulled back by force, and is temporarily separated from the front seat 11 , and the rear seat 13 is rotated to adjust the torque value, and then the rear seat 13 is released, so that the rear seat 13 Rejoined with the front seat 11, the rear end of the rear seat 13 extends axially inward with a chamber 15, and an internal thread 16 is formed on the inner wall of the chamber 15 near the rear end. In this embodiment, the clutch unit 14 has a bolt 141 and a spring 142. One end of the bolt 141 is locked to the rear end of the front seat 11, and the other end is located in the chamber 15 of the rear seat 13. The spring 142 is It is in contact between the bolt 141 and the rear seat 13 to provide the rear seat 13 with the effect of being temporarily separated from the front seat 11 by external force and having elastic force to return to the combined state. Referring to Figures 1 to 4, the accommodating base 20 has a through hole 21 at its axis. One end of the accommodating base 20 is formed with a plurality of insertion holes 22 around the through hole 21. Please refer to the first to fourth figures. The screwdriver heads 30 have various shapes, such as cross, straight, star, hexagon, etc. The screwdriver bits 30 are respectively inserted into each socket 22 of the accommodating base 20, and the accommodating base 20 is placed together with the screwdriver bits 30 in the accommodating chamber 15 of the screwdriver body 10, and Make the front ends of the screwdriver bits 30 face the rear end of the rear seat 13 . Referring to the first to fourth figures, the back cover 40 has an external thread 41 and an anti-slip pattern 42 on its outer peripheral surface. The external thread 41 is detachably screwed together with the internal thread 16 of the driver body 10 to detachably connect the back cover 40 and the driver body 10 to close the chamber 15 . Please refer to the first and fourth figures. The buffer pad 50 is combined with the inner end surface of the back cover 40, so that when the back cover 40 is combined with the screwdriver body 10, the buffer pad 50 can be positioned on the screwdriver. Between the head 30 and the back cover 40, it can reduce the probability of damage that may occur when the screwdriver head 30 and the back cover 40 are in direct contact. In this embodiment, the buffer pad 50 is sponge. Therefore, the above is an introduction to each component of the torque driver 100 provided by a preferred embodiment of the present invention, and then its assembly method and usage characteristics are introduced as follows: First of all, when the user does not need to use the invention, the screwdriver bits 30 are inserted into the receiving seat 20 and stored in the receiving chamber 15 of the rear seat 13. In this way, not only can the storage space be reduced, but the storage space can be reduced. The smaller size can reduce the occupied space and prevent the screwdriver head from being lost, thereby reducing the difficulty of not being able to find the screwdriver head when you want to use it. In addition, when wanting to use the invention or want to replace the screwdriver bits, the user can directly unscrew the back cover 40 to expose the screwdriver bits 30 located in the chamber 15. In this way, the user can The position of the screwdriver head to be taken out can be directly visually known, and the specific screwdriver head can be easily taken out of the chamber 15 to be coupled to the coupling head 12 of the screwdriver body 10 . Therefore, this invention is not only very convenient in operation, but also the procedure of replacing the rotor head is very simple, which can effectively save time. The above disclosures are only the preferred embodiments provided by this invention and are not intended to limit the implementation scope of this invention. All equivalent changes made by relevant skilled persons in this technical field based on this invention shall belong to this invention. Scope covered.
