Description

Technical Field

[0001] The utility model relates to the technical field of hardware components, in particular to a novel screwdriver head sleeve. Background Art

[0002] Screw refers to a screw (foreign name: Screw), which is a tool that uses the physical and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually tighten objects and parts. Screw is a general term for fasteners and a daily colloquial language.

[0003] Metric threads are measured in millimeters, and their tooth angle is 60 degrees. Both American and British threads are measured in inches. The tooth angle of American threads is also 60 degrees, while the tooth angle of British threads is 55 degrees.

[0004] However, when using screws, the screwdriver may have difficulty in cooperating with the bolt. If a common compensating component is used, the length of the compensating component is difficult to adjust, so a specific length needs to be used, which is difficult to adapt to different situations. Therefore, it is necessary to solve this technical problem. Utility Model Content

[0009] The sleeve is provided with a mounting groove, the sleeve is sleeved with a spring, and two ends of the spring respectively abut against the outer side wall of the sleeve and the inner side wall of the mounting groove.

[0010] The cross-section of the inner cavity of the sleeve is respectively prismatic and circular. A magnet is arranged on the sleeve.

[0011] In order to position the length between the sleeve and the sleeve and improve the overall practicality, preferably, a limiting groove is provided on the sleeve, a fixing rod is provided in the limiting groove, a hinge frame is provided on the fixing rod, a limiting plate is fixed on the hinge frame, and the limiting plate cooperates with the limiting ring.

[0012] In order to reduce the possibility of hand slipping during the rotation of the sleeve and improve the overall practicality, preferably, the outer side wall of the sleeve is provided with anti-slip grooves.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a new type of screwdriver head sleeve, which has the following

[0015] Beneficial effects:

[0016] When the screw needs to be used, the new screwdriver head sleeve is first inserted into one end of the sleeve, and the screw cooperates with the circular inner cavity inside the sleeve. Then, the limiting component is toggled to shorten the overall length, thereby adjusting the distance between the screwdriver and the screw so that the screwdriver can be connected to the screw. If the screw or the screwdriver is too long, the two only need to be matched with each other through this structure. Moreover, this structure can adapt to the needs of different lengths, thereby improving the overall convenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5The utility model provides a technical solution: the new screwdriver head sleeve comprises a sleeve 1, a movable sleeve 2 is sleeved on the sleeve 1, a ball socket is arranged in a circular array on the outer wall of the sleeve 1, a rotatable ball 3 is arranged on the ball socket, the inner diameter of the inner wall of the ball socket on the sleeve is smaller than the inner diameter of the ball, the outer wall of the ball 3 cooperates with the inner wall of the sleeve 2, a limiting ring 4 for limiting the ball from escaping is arranged on the sleeve 1, and the limiting ring 4 cooperates with the sleeve 1;

[0025] The sleeve 2 is provided with a mounting groove, and the sleeve 1 is sleeved with a spring 5, and two ends of the spring 5 respectively abut against the outer side wall of the sleeve 1 and the inner side wall of the mounting groove.

[0026] The cross section of the hole of the sleeve is not specifically limited in this embodiment. Of course, in order to facilitate the operation of the screw, further, the cross section of the inner cavity of the sleeve 1 is respectively prismatic and circular, the side facing the screw is circular, and the side facing the screwdriver is polygonal, such as rhombus or polygonal, adapted to the shape of the screwdriver.

[0027] See attached Figure 3 When the screw needs to be used, first insert the screw into one end of the sleeve 1, and the screw cooperates with the circular inner cavity inside the sleeve 1. Then, insert the bolt driver or the replaceable screw head from the other end of the sleeve. Normally, the cross-section of the screw head is polygonal and matches the inner wall. Multiple card points can be set on the screw head. First, move toward the screw through the sleeve, press the spring, and the ball disengages from the restriction of the inner wall of the sleeve. Then, the entire screw head is inserted into the sleeve, and the sleeve is relaxed. The sleeve returns to its position. At this time, the ball returns to its position and clamps the main card point to adjust the distance between the screwdriver and the screw. Different card points can be clamped as needed so that the screwdriver can be connected to the screw. If the screw or screwdriver is too long, they only need to be matched with each other through this structure to improve the overall convenience.

[0028] In this embodiment, the sleeve is provided with the magnet for attracting screws that are not in place.

[0029] In another embodiment, the present invention uses a limiting component to control the length, for example Figure 4 and Figure 5 The sleeve 2 is provided with a limiting component, and the sleeve 1 is provided with a magnet; then the limiting component is moved to shorten the overall length.

[0030] In the utility model, a limiting groove is provided on the sleeve 2, a fixing rod 6 is provided in the limiting groove, a hinge frame 7 is sleeved on the fixing rod 6, a limiting plate 8 is fixed on the hinge frame 7, and the limiting plate 8 cooperates with the limiting ring 4. Through the above-mentioned limiting assembly, the limiting assembly can adjust the length between the sleeve 2 and the sleeve 1, and position the length between the sleeve 1 and the sleeve 2, thereby improving the overall practicality.

[0031] In the present utility model, anti-skid patterns are provided on the outer side wall of the sleeve 2. The anti-skid patterns can effectively reduce the hand slipping during the rotation of the sleeve 2, thereby improving the overall practicality.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
