Description

M249770 V. Creation instructions (1) [The creation of the new type is related to the screwdrivers of various types of screwdrivers. [Prior technology] According to our first technical field] The screwdriver structure ’, especially a kind of ten-door clamping structure improvement. The speed card said: the precision screwdriver series includes: the screwdriver handle known before, the heart is a through hole, in which the cone, such as the application number head, is simply inserted into one end to make a contraction, open to the bottom of the four notches with a warp recess The groove is formed at one end, and two of the outrigger ends should be pulled away from each other. Then the structure of the holding head is changed to the clamping head. The main handle and the front end of the sleeve head form a clamping position for each driving rod, such as a barrel head. Inside, so that the claw head can be embedded in the recessed buckle part, change the driving head, and then apply for a buckle, the edge bending induced punching number 8 7 is good, the key feature is 8 5 2 0 3 The head, the front end is a symmetrical straight spring buckle, the buckle ring has an opening, and the buckle ring portion, and the two extension arcs: outwardly open the groove. 2Patent name 2 15 4 The patent case mainly includes a precision levy: the sleeve head ring is surrounded by a number of concave shoulders, and the inside of the sleeve head is worn 8 3 4 This patent case is The tapered back concave notch extends from the inside of the two outriggers by a reed. There are grooves on the side of the precision lifting tool body. In addition, it can be constructed by clamping the sleeve head. No. 8 8 is provided with a spring and a groove to constrain the spring and the head. Use the misfit head to hold the clamping head separately from the body and shoulder and push or pull the head before matching the horse area. The sleeve Enter the body, and make the moving rod properly reach the simple and convenient name. The middle and straight roll arms, the face tongs and a grip sleeve 1 = 7, and the lost place is easy to change. 7 8 Patent name

m 9205 丨 6 snap screw lock.ptd creation instructions (2) __ Improved sub-clamp structure, this patent case is an improvement, the end of the rotating shaft is pivoted = = from the front of the closed structure There are screwdriver heads in the group, the main characteristics of which are in wide; :::: the body corresponding to the shape of the screwdriver head is recessed with a profile σ, and the upper end of the front end of the movable shaft is provided with a recessed groove, And: the outer edge of the mouth spins to the shape of the sleeve, and the concave edge groove must be set with == through-: bit pearl stomach 'to make the buckle bead from the tapered hole to the shape sleeve == clip f buckle in the screwdriver head Those who have pre-set ring grooves at the end section promote ^ 1 to make it easier to invert, replace the screwdriver head, and reduce the precision of the screwdriver. The practical purpose of the screwdriver is to achieve the product of f. The number of people reduced the body size of the box. The structure has a variety of well-used and disadvantaged products that engage with various screwdrivers. Ding Caizhi, .., two inspections, finally there is a change [new content] The reason is 'this creative department is about a kind of people with less inclusion--screwdriver is located at the end of the connector, ": two' Main: card slot, card system The groove is provided with a thread; 4 :: The end of the fitting part is provided with a sloping groove at the end ... The sloping system of the head is connected with ::::: = The other screwing part can be screwed to the card # ^ 子 之The slot fits together; a screw lock makes the 刼; -s, a 'hunting this' screwdriver can prevent the screwdriver from coming out of the screwdriver due to the screw lock of the screwing part, and the screw-toe 4a makes the screwdriver turnable The effect of moving the screwdriver head is 5 pieces to the chute of the cripple. In order to make your reviewers better understand and agree with the work of this creation: The temple sign and the effect are Niu Ping and Jiabei.
