Description of the Invention: [Technical Field] The present invention mainly discloses a pressure gauge, and more particularly to a pressure gauge which can display different pressures on both sides. [Prior Art] The common pressure gauges belong to the measurement of a single object to be tested. In the bicycle field, it is usually used to measure the pressure value of the fork before and after the suspension, and the front fork of the suspension. Because the load is lighter, the required pressure value is lower, and the ideal pressure value is about 100 psi. In comparison, the rear fork has a heavier load and the pressure value is larger, and the ideal pressure value is about 3 〇〇 pSi. When the equivalent shock absorber front fork and the same pressure gauge are used after the shock absorber, because the pressure values of the two are very different, the pressure gauge is not ideal and the misjudgment is easy. When the pressure f value of 100 psi is represented by a dial of 0 to 300, it is easy to quickly judge the pointer indication because the scribe is too thin; and when the pressure value is 3 psi, it is represented by a dial of 1 〇〇. Since the maximum value is only scored to 1〇〇, the pointer will be straight %: turn, the operator must a ten-nose hand rotation to determine the pressure value 'is really not easy to use. Check another type of pressure gauge that can be displayed on both sides. Please refer to China's patent number No. M264493 "Modified double-sided pressure gauge structure" to reveal a pressure = table with two dials on both sides. The hands of the face dial are rotated in a clockwise direction, and no misjudgment occurs when the user views. Although this is the case, the dials on both sides of the pressure gauge are in the same state. It is known that the ten is only applicable to the n-force value. The user applies the shock absorber to the fork on both sides of the pressure gauge. The first surface 30 and the first body 13 are fixed to one side of the body 11 , and the first shaft 22 is the center of the first surface 30 , and a pointer 31 is attached. The second surface 40 is scored with a scale of 0 to 100 less pressure values and is suitable for measuring the shock absorber front fork pressure value of the bicycle. The second surface 40 and the second body 14 are also fixed to the other surface of the body 11. The second shaft 23 is the axis of the second surface 40, and a pointer 41 is attached. The housing 50 is provided with a first surface 51 and a second surface 52. The housing 50 is sleeved on the joint 10, the reduction gear train 20 and the two surfaces 30, 40. The housing 50 is provided with a first The protective sheet 53 closes the first surface 51, thereby protecting the first surface 30, and a sheath 54 is further sleeved on the first protective sheet 53 while the first protective sheet 53 and the sheath 54 are fixed to the housing 50. The second surface 52 of the housing 50 is provided with a second protective sheet 55 to protect the second surface 40. The two protective sheets 53, 55 are in a see-through shape. Referring to Figures 4, 5 and 6, a schematic view of the reduction gear train 20 and the first surface 30 of the present invention is shown. When the gas enters the Baden tube 12 via the joint 10, the Baden tube 12 is deformed by the pressure of the gas, and the swing arm 24 is swung by the connecting member 242, and the swing arm 24 drives the first gear 221 of the first shaft 22. Rotating, at this time, the first surface 30 centered on the first shaft 22, by which the pointer 31 is rotated to the displayed pressure value. Referring to Figures 7 and 8, a schematic view of the reduction gear train 20 and the second surface 40 of the present invention is shown. When the swing arm 24 drives the first shaft 22 to rotate, the second gear 222 of the first shaft 22 also rotates at the same time, and the second gear 222 drives the third gear 231 to rotate, so that the second shaft 23 is also followed. Rotating, at this time, 1336396 with the second surface 4〇 of the first glaze as the axis, the pointer 41 of the two surfaces 40 is rotated to the displayed pressure: value: the second axis 23 makes the first surface 30 and the second surface 4 The axis of the 〇 3 3° is the first, the second surface:: the axis = Ϊ·! 3 rim ― the second gear 222 of the shaft 22 drives the Qing; 2: 1:::
