[0021] A screwdriver of novel structure includes a screwdriver handle 1, a ratchet assembly 2 is fixed at the front end of the screwdriver handle 1, a screwdriver bit replacement plug-in hole 201 is provided on the ratchet assembly 2, a spare screw bit storage bin 101 is provided in the screwdriver handle 1, the storage bin opening of the spare screw bit storage bin 101 is arranged backward, a rear cover 3 for blocking the storage bin opening is detachably connected at the rear end of the screwdriver handle 1, a spare screw bit storage seat 4 is provided on the inner side of the rear cover 3, a spare screw bit 5 is plugged and stored in the plug hole of the spare screw bit storage seat 4, and the spare screw bit storage seat 4 and the spare screw bit 5 extend from the storage bin opening into the spare screw bit storage bin 101. The spare screw bit 5 is designed with various models, such as: straight-shaped, cross-shaped, etc.

[0022] like Figure 1-6 As shown, when the screwdriver of the present invention is not in use, such as during transportation, handling, or storage, the spare bit 5 can be connected to the spare bit storage seat 4 and inserted into the spare bit storage bin 101 , and the rear cover 3 can be rotated and tightened.

[0023] When in use, the rear cover 3 is opened, the spare screwdriver bit 5 of the required model is taken out, and installed into the screwdriver bit replacement plug hole 201, and the basic function of screwing a screwdriver can be realized by using the utility model.

[0024] A connecting rod 6 and an inner baffle plate 7 extending into the bit storage bin 101 are fixed to the spare bit storage seat 4 , and the connecting rod 6 is sleeved in the inner baffle plate 7 .

[0025] Specific as Figure 1 and Figure 2 As shown, under this structural condition, the utility model can design the screwdriver handle 1 into a shorter screwdriver handle 1, and the spare bit storage bin 101 in the screwdriver handle 1 is also smaller. Only the inner baffle plate 7 is fixedly connected to the inner side of the rear cover 3. The spare bit 5 is stored in the area between the inner baffle plate 7 and the rear cover 3, and is plugged into the socket of the spare bit storage seat 4. The inner baffle plate 7 can prevent the spare bit 5 from accidentally falling. When the rear cover 3 is removed, the inner baffle plate 7 can be taken out together with the spare bit 5.

[0026] A second spare bit storage seat 8 is fixed inside the spare bit storage seat 4 , an inner baffle 7 is fixed to the inner end of the second spare bit storage seat 8 , and a connecting rod 6 is sleeved in the second spare bit storage seat 8 and the inner baffle 7 .

[0027] Specific as Figure 3 , 4 As shown in Figure 5, under this structural condition, the utility model can design the screwdriver handle 1 into a longer screwdriver handle 1, and the spare bit storage compartment 101 in the screwdriver handle 1 is also relatively large. The spare bit storage seat 4 on the inner side of the rear cover 3 is connected to a second spare bit storage seat 8, and the inner baffle 7 is connected to the second spare bit storage seat 8. In this solution, more spare bits 5 of different models can be stored and prepared together through the spare bit storage seat 4 and the second spare bit storage seat 8.
