The invention discloses a mechanical hand clamp and a mechanical hand. The mechanical hand clamp comprises a mounting base. Two drive connecting rod frames are symmetrically mounted on the mounting base, bearing blocks are mounted on the drive connecting rod frames, anti-shake mechanisms are mounted on the surfaces of the bearing blocks, through clamping grooves are formed in the side faces of thebearing blocks, and pushing mechanisms are mounted in the through clamping grooves. The equipment is provided with the anti-shake mechanisms, when the mechanical hand needs to clamp an object, the object is preliminarly fixed firstly by preliminary clamping blocks, after the object is fully clamped by the preliminary clamping blocks, pushing blocks can push away stretching fixing blocks, the clamped area of the object is increased, and even when the mechanical hand or the clamped pipeline shakes due to misoperation of a user, as the clamped area of the object is large and the object is simultaneously fixed by the preliminary clamping blocks and the stretching fixing blocks, the object cannot easily disengage from the clamp due to shaking and oscillating.

The invention relates to the field of bookracks, and particularly relates to a multifunctional bookrack. The bookrack comprises a pedestal, a support mechanism, a placement mechanism, a blocking mechanism and a braking mechanism. Via the installation of the pedestal, the support mechanism can be more stably installed, so that the support mechanism does not tilt easily; meanwhile, via the installation of the support mechanism, the placement mechanism can be used flexibly, so that books are more convenient to place and take, and placement efficiency and taking efficiency of the books are improved; meanwhile, via the installation of the braking mechanism, rotation of the placement mechanism can be conveniently controlled, so that the placement mechanism does not rotate randomly, and thus thebooks are prevented from dropping down; and the blocking mechanism is installed on one side of the support mechanism, and via the installation of the blocking mechanism, hiding or storage of the precious books is facilitated, the books are effectively prevented from being lost and damaged, and meanwhile, outside dust is effectively isolated via the blocking mechanism, and the dust is prevented from entering to damage the books.

The invention provides a mixer with a good damping effect, and relates to the technical field of industrial machinery. The mixer with the good damping effect comprises an outer box, a mixing box is arranged in the outer box, fixing plates are fixedly connected to the left and right sides of the mixing box, the centers of the tops of the fixing plates are connected with lead screws in a threaded mode through thread holes. Limiting grooves are formed in the left and right sides of the inner wall of the outer box, sliding rails are fixedly connected into the limiting grooves, and the sides, awayfrom the mixing box, of the fixing plates are movably connected with the side faces of the sliding rails. Bearings are arranged at the two ends of the bottom of the inner wall of the outer box in an inlaid mode. The mixer with the good damping effect is provided with the fixing plates, the lead screws, the limiting grooves, first groove wheels and a second groove wheel, the vibration frequency canbe changed, materials in the mixing box can be fully mixed, the materials are not prone to being left in the inner wall of the mixing box, the mixing is more even, the mixing degree of the materialsis increased, and the output of the materials is improved.

The invention discloses a convenient garbage can. The convenient garbage can has a can cover (1), a can body (2), an inner can (3) and a pedal switch (4), and is characterized in that a lock (5) is arranged below the inner can (3); the vertical movement of the inner can (3) can be controlled through the effect of the lock (5), so that an opening of a garbage bag can be loosened, users can easily take out the bag fully filled with garbage in the garbage can, and the convenient garbage can brings excellent use effect to the users.

A device for tire pressure monitoring belongs to the technical field of automobile parts; it includes a tire hub, a limit device and a detection device, wherein an inner ring is formed on the surface of the tire hub, and a through hole is formed on the surface of the inner ring, The through hole is arranged obliquely to the inner side of the tire hub, the limiting device is arranged on both sides of the through hole, and one end of the detection device is inserted into the interior of the limiting device; The detection device can be clamped inside the limit device, and the top of the detection device can protect the detection device to avoid damage to the detection device after the car tires run out of air. Pressure through holes are opened on the left and right sides of the power box to avoid External pressure will punch the box cover, and at the same time, there is an installation gap inside the limit device, and the installation gap and the maintenance cover on the detection device correspond to each other, so that the limit device will not affect the power box when it is disassembled.

The invention, which belongs to the technical field of monitoring devices, in particular relates to a remote sensing monitoring system of an ecological environment. The system comprises a fan plate. Aconnecting plate is welded on one side surface of the fan plate; a motor is fixedly connected to the upper surface of the connecting plate by bolts; and a rotating tooth is in transmission connectionwith the output end of the motor. When the system is in use, the whole device is arranged at a certain position by using a support rod below a base block; the motor is started; a rotating rod and a shooting device body are driven by the rotating teeth, an auxiliary gear, and a movable tooth to make corresponding rotation, thereby completing dynamic monitoring of the ecological environment and themonitoring process of the ecological environment under lenses at different angles. With a second baffle at one side of a protection board, the shooting device body is protected well; and the second baffle is divided into three parts and extends downwardly gradually to the outer side, so that the rainwater is prevented from falling on the shooting device body.

This invention discloses a filter method and device of motor lube, utilizing different gravities of lube and grease to separate them with same centrifugal force including two lubricant pumps, a tray, a filter and a pipe, in which, an inlet of one pump is connected with a tank by the pipe, the outlet port decenter is aligned with the disk of the filter, the tray is connected with the inlet of second pump by pipe, avoiding grease and fine particles coming into the lubricating system due to the second filtration before thelube enters into the lubricating system with the advantage of reducing exchange time of lube, increasing life time of the motor.

The invention discloses a supporting device for planning of cultural activities. The supporting device comprises two bases, wherein supporting mechanisms are welded to the outer walls of the tops of the two bases; each of the supporting mechanisms comprises a supporting column; channels are arranged on the outer walls of the tops of the supporting columns in the height direction; sliding plates are mounted in the channels in a sliding manner; screw rods are connected to the outer walls of the tops of the sliding plates through bearings; limiting threaded rings are welded to the outer walls ofthe top ends of the supporting columns; limiting rings are connected to the outer walls of the top ends of the screw rods in a sleeving manner; first fixed rings are connected to the outer walls of the lower parts of the supporting columns through the bearings; a first supporting frame having an L-shaped structure is welded to the outer wall of one side of each of the first fixed rings; and secondfixed rings are connected to the outer walls, positioned above the first fixed rings, of the supporting columns through the bearings. The supporting device disclosed by the invention can be folded, so that space occupation is reduced, and the supporting device is convenient to transfer and carry; vacuum sucking discs are sucked on the ground, so that the device cannot easily fall down, and thus,a fixing effect of the device is improved.
