DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings. For better understanding, the orientation of the present invention is described according to the orientation shown in the accompanying drawings and cannot be understood as a limitation of the present application; the following terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0017] See also Figures 1 to 5 The utility model provides an embodiment: a replaceable convenient telescopic double-headed screwdriver, comprising an upper shell 1, a lower shell 2 and a metal rod 607, wherein the upper shell 1 covers the upper part of the lower shell 2, a partition 3 is arranged at the middle position of the bottom of the lower shell 2, long convex strips 4 are arranged on both sides of the partition 3, sliders 5 that can slide on the long convex strips 4 are arranged on both sides of the partition 3, the metal rod 607 is fixed on the slider 5, a first opening 8 corresponding to the position of the metal rod 607 is opened at the front end of the lower shell 2, a telescopic component 6 that can control the movement of the slider 5 is arranged on the slider 5, two first long strip openings 608 are opened on the upper shell 1, buttons 609 are arranged in the long strip openings, and the button 609 is connected to the telescopic component 6. When the screwdriver is needed, the button 609 is pushed forward manually to drive the telescopic assembly 6 to provide power to drive the slider 5 to move from the rear end of the lower shell 2 to the front end of the lower shell 2, thereby driving the metal rod 607 fixed on the slider 5 to extend from the first opening 8. After using the screwdriver, the button 609 is pushed backward manually to drive the telescopic assembly 6 to provide power to drive the slider 5 to move from the front end of the lower shell 2 to the rear end of the lower shell 2, thereby driving the metal rod 607 fixed on the slider 5 to retract from the first opening 8 into the lower shell 2, so that the metal rod 607 in the screwdriver can be retracted and rebounded to freely switch between two different blade heads. The partition 3 divides the cavity of the upper shell 1 and the lower shell 2 into two cavities. The metal rods 607 of the two cavities can be controlled to retract and retract separately. The metal rod 607 of the left cavity is controlled to retract and retract by pushing the button 609 on the left, and the metal rod 607 of the right cavity is controlled to retract and retract by pushing the button 609 on the right.

[0018] Please continue reading Figure 5As shown, in one embodiment of the utility model, the telescopic assembly 6 includes an arc strip 615 and a fixed plate 614, a trapezoidal protrusion 601 is fixed to the outer side of the arc strip 615, a groove 602 is provided on the outer side of the lower shell 2, a dovetail groove 603 that matches the trapezoidal protrusion 601 is provided in the middle position of the groove 602, a boss 604 for placing the fixed plate 614 is provided on the outer side of the upper shell 1 and the partition 3, a second long strip opening 605 is provided on the fixed plate 614, a support rod 606 is fixed on the slider 5, and the One end of the support rod 606 is located in the second long strip opening 605, and a baffle 610 is fixed to the lower surface of the fixed plate 614. The baffle 610 is located on both sides of the second long strip opening 605, and an elastic rope 611 is sleeved on the baffle 610. A pressing block 612 is fixed to the lower surface of the outer side of the fixed plate 614, and a cut angle is set at one end of the pressing block 612 pressed together with the arc strip 615. A block 613 for limiting the arc strip 615 is set on the outer side of the slider 5, and the button 609 is fixed on the fixed plate 614. The arc strip 615 is engaged with the dovetail groove 603 on the outer side of the upper shell 1 through the trapezoidal protrusion 601. The trapezoidal protrusion 601 and the dovetail groove 603 form a dovetail structure. When the metal rod 607 is extended and retracted in the lower shell 2, the slider 5 is located at the rear side of the rear end of the arc strip 615 and is limited by the arc strip 615. By pushing the button 609 forward, the fixed plate 614 is driven to move forward. The support rod 606 is located in the elastic rope 611 sleeved on the baffle 610. When the button 609 is pushed, the elastic rope 611 is stretched to generate elastic force because the position of the slider 5 is fixed. The lower end part of the end of the arc strip 615 is limited by the block 613. When the button 609 is pushed, the pressure block 612 at the rear end of the lower surface of the fixed plate 614 will slowly squeeze the upper end part of the end of the arc strip 615 toward the outside, releasing the slider 5. The limit of the elastic rope 611 is that the support rod 606 also moves in the second long strip opening 605 due to the elastic force in the elastic rope 611. At the same time, the slider 5 moves forward in the lower shell 2. To guide the movement of the slider 5, the slider 5 moves to the front side of the front end part of the arc strip 615. The slider 5 is limited at the front end of the arc strip 615. At this time, the screwdriver can be used normally. When it is needed, the button 609 is pushed backward to drive the fixing plate 614 to move backward. The elastic rope 611 is stretched to generate elastic force because the position of the slider 5 is fixed. When the pressure block 612 at the front end of the lower surface of the fixing plate 614 slowly squeezes the end of the arc strip 615 outward, the limit of the slider 5 is released, allowing the slider 5 to move backward in the lower shell 2 and move back to the rear side of the rear end of the arc strip 615, thereby driving the metal rod 607 to retract.

[0019] Please continue reading Figure 5As shown, in one embodiment of the utility model, a front cover 7 is fixed to the front end of the upper shell 1 and the lower shell 2, and a second opening 9 is opened on the front cover 7 and is opposite to the first opening 8. A rear cover 10 is fixed to the rear end of the upper shell 1 and the lower shell 2. The front cover 7 and the rear cover 10 can better fix the upper shell 1 and the lower shell 2, and the front cover 7 can deepen the fixation of the metal rod 607 and reduce shaking during use.

[0020] Please continue reading Figure 5 As shown, in one embodiment of the utility model, the upper shell 1 and the lower shell 2 are both provided with anti-sliding blocks 11. The upper shell 1 and the lower shell 2 are provided with a plurality of anti-sliding blocks 11, which can reduce slipping when holding a screwdriver.

[0021] The utility model has the following working principle: when it is necessary to use a screwdriver, a button on one side is pushed forward to drive the fixing plate to move forward, and while pushing the button, a pressure block at the rear end of the lower surface of the fixing plate will slowly squeeze the end of the arc-shaped strip plate outward, thereby releasing the limit on the slider, and at this time, due to the elastic force in the elastic rope, the slider will move forward in the lower shell body, thereby driving a metal rod on one side to extend out; when it is necessary to replace the metal rod bit, the button on the changed side is pushed backward to drive the fixing plate to move backward, and the pressure block at the front end of the lower surface of the fixing plate will slowly squeeze the end of the arc-shaped strip plate outward, thereby releasing the limit on the slider, allowing the slider to move backward in the lower shell body and move back to the rear side of the rear end of the arc-shaped strip plate, thereby driving the metal rod to retract, and pushing the button on the other side to allow the metal rod on the other side to extend out for operation.

[0022] The above description is only a preferred embodiment of the present utility model and cannot be understood as a limitation of the present application. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the present utility model.
