The invention provides a double guide-bar telescoping mechanism for motor vehicle equipment, which is characterized by comprising a bottom plate, a mounting plate, a mounting block, a connecting post,a push rod, a connecting block, a pulling member, a clamp, a penetrating plate, a vertical plate, penetrating holes, mounting holes, in-place stop blocks, guide bars, a mounting rod, a movable jointand nuts, wherein the mounting plate is mounted on the upper side of the bottom plate by bolts; a mounting block is mounted at one end of the mounting plate; the clamp is mounted on the mounting block; non-slip lines are formed in a plastic shell; the other end of the mounting plate is welded with the connecting post; the connecting post is connected with the clamp through the pulling member; a through hole is formed in the connecting post; the connecting post is fixed with the connecting block through the through hole; the connecting block is connected with the pulling member; the push rod isinternally provided with internal threads; and the push rod is connected with a screw through the internal threads. According to the double guide-bar telescoping mechanism provided by the invention,the displacement of the guide bars are restricted, and at the same time, the movable joint and internal parts thereof are protected to avoid parts damage.

The invention discloses an electronic product adjusting type storage device with a fixing effect. The storage device comprises a main body and a circular groove, the bottom end of the inner side of the main body is connected with a rotating wheel, a conveying belt is arranged outside the rotating wheel, moreover, a supporting rod is fixed at the upper end of the conveying belt, the top end of thesupporting rod is connected with a rotating belt, moreover, a pressing plate is arranged at the upper end of the rotating belt, a screw rod is fixed inside the pressing plate, a supporting plate is arranged at the upper end of the screw rod, moreover, the top end of the supporting plate is connected with a spring, and an interlayer plate is arranged at the top of the spring. According to the electronic product adjusting type storage device with the fixing effect, the pressing plate and the supporting plate can be combined by screwing the screw rod, moreover, the use space of the pressing plateand the supporting plate can be increased by screwing the screw rod so that an electronic product between the pressing plate and the supporting plate can be firmly fixed therein, then the phenomenonthat the special electronic product falls off can be prevented, so that the certain fixing and protection effects are achieved for the storage protection of the electronic product.

The invention relates to a placing device for a TSP blast hole emulsion explosive and an operation method. The placing device comprises a stainless steel protective sleeve, an in-sleeve separation sheet is fixed to the interior of the stainless steel protective sleeve, a sleeve open slot is formed in the front end of the stainless steel protective sleeve, a separation sheet hole is formed in the in-sleeve separation sheet so that a sleeve core connecting rod can penetrate, the two ends of the sleeve core connecting rod are connected with an explosive placing hopper and a rotary handle, and the sleeve core connecting rod, the explosive placing hopper and the rotary handle are fixedly connected into a whole. The depth of the portion, entering a blast hole, of the sleeve core connecting rod can be adjusted through extraction according to measurement of a dividing rule and the rotation angle of the rotary handle can be acquired through an angle measurement device. By the adoption of the novel placing device for the TSP blast hole emulsion explosive and the operation method, the emulsion explosive and an electronic detonator exploder can not be affected by slurry and gravel hole blockage under the protection of the rigid sleeve, and the success rate of TSP blast hole detonation is increased; meanwhile, the device is simple in structure and convenient to operate, the explosive can be transported to the position of the preset depth of the blast hole only by extracting and rotating the sleeve core connecting rod and placing efficiency of the TSP blast hole emulsion explosive can be greatly improved.
