Technical Field

[0001] The present application relates to the field of screwdrivers, and in particular to a straight-handled screwdriver. Background Art

[0002] A screwdriver, also known as a screwdriver, is a common tool used to turn a screw to put it in place. It usually has a thin wedge-shaped head that can be inserted into the slot or notch of the screw head. Screwdrivers include combination screwdrivers, which are screwdrivers with the screwdriver head and handle separated. When installing different types of screws, you only need to replace the screwdriver head.

[0003] The Chinese patent with the authorization announcement number CN103707250B discloses an electric screwdriver, which includes a hollow cylindrical housing, a motor, a gear output shaft connected to the motor, a tail cover, a battery and a negative contact sheet, wherein the gear output shaft is used to connect to the screwdriver head, the tail cover is arranged at one end of the housing away from the gear output shaft, and the maximum diameter of the housing is 24 mm to 35 mm. It also includes a special-shaped spring connected to the battery and arranged in the tail cover, a battery ring with one end connected to the special-shaped spring and the other end connected to the negative contact sheet, and the tail cover is snap-fitted with the housing.

[0004] With regard to the above-mentioned related technologies, when a screwdriver is used in different scenarios, it is necessary to replace different types of screwdriver bits. The screwdriver bits are small in size and are easily lost during carrying, which in turn affects the screwdriver's adaptability to different usage scenarios. Utility Model Content

[0005] In order to facilitate the storage and carrying of screwdriver bits and reduce the loss of screwdriver bits, the present application provides a straight-handled screwdriver.

[0006] The straight handle screwdriver provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution and adding a mounting cover, it is possible to avoid damage to the operator caused by the screwdriver rod when not in use. When not in use, several different types of screwdriver bits can be stored in the placement gap, which is convenient for storing screwdriver bits of different types in turn, reduces the loss of screwdriver bits, and allows the screwdriver to adapt to different usage scenarios.

[0009] Optionally, the storage component includes a plurality of cylinders, the length direction of the cylinders is consistent with the length direction of the screwdriver rod, and the plurality of cylinders are distributed in the mounting cover in sequence along the circumference of the mounting cover. One end of the cylinder along its length direction is connected to the inner wall of the mounting cover. One cylinder is used to place a screwdriver bit, and the inner wall of the cylinder is interference connected with the screwdriver bit.

[0010] By adopting the above technical solution, different types of screwdriver bits are placed in different cylinders, so as to facilitate the storage of multiple screwdriver bits in the placement cavity.

[0011] Optionally, an insertion rod is connected inside the installation cover, the central axis of the insertion rod is colinear with the central axis of the installation cover, the end of the insertion rod away from the installation cover is embedded in the slot, and the end of the insertion rod away from the installation cover is sleeved with a flexible layer, the flexible layer is used to contact the inner wall of the slot, and the flexible layer is set with elastic material.
